A process for the production and purification of succinic acid

摘要: A process for producing and purifying succinic acid comprises growing a succinate salt-producing micro­organism on an inexpensive substrate containing carbohydrate, other nutrients, sodium ions tryptophan under CO₂ partial pressure until most of the carbohydrate is converted to succinate. The fermentation broth then electrodialyzed recover concentrate salt in aqueous stream which subjected water-splitting electrodialysis form base product. resulting product treated first with strongly acidic ion exchanger remove any or cations weakly basic free sulfate sulfuric obtain highly purified
